Home Depot has a 100' 5/8th auger rental. I think I'll give it a go when I go get the stuff for a new baffle. After running the auger, would it be a good idea to irrigate the line with a garden hose? That might allow for some crap to run out. If I can't clear this thing on my own, I really am on the hook for a professional field rebuild and that's just not an option right now. / side note: tank is 1200 gal.
